Hi, I'm afraid I still don't understand exactly what you need. However, I still think you shouldn't use the approach with the <trh:tableLayout>, etc. (Should you need *some* HTML for layout of your page, with Facelets you can use HTML in your Facelet, so you don't need any <trh:...> tag for that anymore.)
If you want to use JSF, you should use JSF components that do the hard work for you. You can search the Trinidad, Tomahawk and Tobago libraries or other component libraries for a component that suits your needs. If nothing can be found, you can create your own JSF component. If you prefer to be super flexible in the HTML output, you should perhaps consider a framework that isn't component based, like JSF.
